I can't buy an Adire driver over the internet unless I want to pay around 60% more due to taxes and shipping. Im searching for an inexpensive yet good driver to begin a DIY proyect and I found the HED12 for about 85 bucks, I know it is not a Shiva, but I managed to get this specs. Are they any good for home use?
